Introduction: Musculoskeletal Disorder (MSD) is an injury that affects the movement of human body systems such as muscles, tendons, ligaments, nerves, blood vessels, and others. The prevalence of MSDs in Indonesia is 11.9% based on diagnosis and 24.7% based on symptoms. MSDs prevalence is 31.2% based on employment among farmers, fishermen, and workers.
